Hi there, I would be happy to assist with the design of a low-cost 150 L agricultural drone for spraying applications. With expertise in mechanical design, CAD modeling, and engineering analysis, I can help develop a robust and cost-efficient UAV platform suitable for agricultural operations. Approach: • Define system requirements including payload capacity, tank volume (150 L), flight time, and spraying coverage. • Conceptual design of drone configuration (likely octacopter or heavy-lift multirotor for stability and high payload). • Structural design of frame, landing gear, tank mounting, and spraying mechanism. • Selection and sizing of propulsion system (motors, ESCs, propellers) based on thrust-to-weight calculations. • Integration of tank, pump, spray nozzles, and piping system. • CAD modeling of full assembly and component layout. • Basic performance calculations for lift, power consumption, and flight endurance. • Preparation of manufacturing-ready design documentation. Deliverables: • Complete 3D CAD model of the drone assembly • Component selection and bill of materials • Structural layout and frame design • Spraying system integration design • Technical drawings for manufacturing • Basic performance and design calculation report Timeline: To be determined after discussing project scope. Budget: Open to negotiation based on complexity. Looking forward to collaborating on this project. Let’s connect to discuss further. Best regards, Arati M.

Hello! I am highly interested in the challenge of designing a 150L heavy-lift agricultural drone that prioritizes affordability—a rare balance where many projects fail by over-specifying expensive aerospace components. Having engineered heavy-lift UAV frames, I know the secret to low-cost scaling lies in optimizing the thrust-to-weight ratio through clever airframe geometry and open-source stacks rather than proprietary, high-margin hardware. My experience ensures we can achieve the necessary lift capacity while maintaining a Bill of Materials (BOM) that makes commercial sense for wide-scale agricultural deployment. To tackle this, I will develop a modular hybrid airframe using a combination of reinforced aluminum alloys and localized carbon fiber to provide structural rigidity for the 150kg+ payload at a fraction of the cost of a full composite build. I will specify high-torque, large-diameter brushless motors (15-20kW class) paired with high-voltage industrial ESCs to maximize efficiency and reliability. The system will run on the ArduPilot ecosystem via a Cube Orange flight controller, allowing for advanced terrain following and mission planning without recurring licensing fees. Additionally, I’ll design a simplified, high-flow pumping system utilizing PWM-controlled logic for precise application rates without the need for expensive, specialized flow sensors. Given the payload, are you considering a coaxial X8 configuration for better stability, or a flat octocopter for easier maintenance? Also, do you have a specific target for the maximum takeoff weight to comply with local regulations? I’d love to discuss your vision for the propulsion power source and can hop on a call whenever you’re ready to align on the technical roadmap.

✅✅✅ Agricultural UAV Systems & Heavy-Lift Drone Design Engineer ✅✅✅ Hi there, I have experience designing heavy-lift UAV platforms and integrating COTS flight-control ecosystems such as Pixhawk with ArduPilot for autonomous agricultural operations. My work includes payload systems, pump-based spraying modules, telemetry logging, and structural UAV frames optimized for high payload efficiency and field serviceability. My approach is to design a lightweight but strong modular frame for the 150 L payload using proven heavy-lift configurations, integrate Pixhawk/ArduPilot avionics with RTK GNSS for precise waypoint missions, and select off-the-shelf motors, ESCs, pumps, and PCBs to keep the BOM cost-effective and easy to source. The spray and seeding systems will be calibrated for ±5% application accuracy. A few questions: Do you prefer octocopter or X8 configuration for redundancy? What target flight time is expected at full load? Will RTK positioning be required for precision agriculture mapping? I am ready to start immediately. Best regards

Hi, I'm excited about the opportunity to design a low-cost agricultural drone with a 150-litre capacity. Your vision for a budget-friendly yet efficient platform resonates with my experience in aerospace engineering and product design. I specialize in creating solutions that utilize off-the-shelf components, ensuring affordability while maintaining performance. For this project, I'll focus on utilizing commercially available PCBs, motors, and sensors to optimize the bill of materials (BOM). My approach includes integrating the Pixhawk or ArduPilot for flight control, coupled with a reliable spraying mechanism and a flexible siembra module to cater to a variety of applications, from cereals to vegetables. The deliverables will include detailed CAD files, comprehensive BOM with supplier links, wiring diagrams, and ground-control documentation. I propose a timeline of 6-8 weeks for the initial prototype, with iterative testing to ensure compliance with your acceptance criteria. What specific features would you prioritize in the drone's operational capabilities? Best regards, Dejan

Hello, I can help design the 150 L agricultural drone platform, focusing on off-the-shelf components to keep the BOM affordable. I will provide: • SolidWorks CAD model of the heavy-lift frame with basic stress checks • BOM with readily available motors, Pixhawk/ArduPilot electronics, pumps, and sensors • Payload system layout for spraying and the seeding module • Wiring diagrams and integration notes for autonomous missions and logging Estimated timeline: 2–3 weeks for the initial design package. Quick question: Do you prefer an octocopter or coaxial X8 configuration for the 150 L payload, or should I determine the best layout?

Hey there! I saw your post for the 150L heavy-lift drone and I’m definitely interested. As a licensed structural engineer and architect, I specialize in designing rugged, high-capacity frames that actually hold up under load. I’m a big believer in using COTS parts like Pixhawk/ArduPilot to keep maintenance simple for the end-user. I can handle the CAD work, stress analysis for that 150kg payload, and the plumbing for the "siembra" and spray modules. I’ll focus on a BOM using off-the-shelf PCBs and hobby-standard motors so you aren't stuck with proprietary tech. I've worked on autonomous indoor robotics and large-scale permit-ready engineering before, so I’m comfortable with the technical documentation and flight logs you need. Let’s chat about getting this project off the ground!

As a Mechanical Design Engineer with significant experience in manufacturing technology and core skills in designing for practicality, functionality, and efficiency, I believe I am uniquely qualified for your project. My mastery in SolidWorks and PTC Creo will allow me to create both detailed 3D models and technical drawings, which are crucial for the development of your agricultural drone. Moreover, my strong understanding of manufacturing processes is instrumental in my design choices—I don't only create CAD components that look good but components that can be produced efficiently and cost-effectively. I'm confident that my focus on using commercially available PCBs, motors, pumps, and sensors instead of custom boards will significantly help keep the BOM low for an affordable product. In terms of heavy-lift or agri UAV experience, although I haven't designed these exact drones before, my knowledge and skills in mechanical engineering apply across a wide range of projects. I'm adept at translating concepts into precise, manufacturing-ready CAD models and technical drawings—a skill set that would be enormously valuable for the delivery of your project's acceptability criteria. Let's turn this concept into a reliable field-ready product while ensuring costs are tightly managed.
